Places to Get Help
There should be information to cover many situations on this Wiki. If you can't find it here, but do find it elsewhere, consider helping future visitors by adding the information in some relevant location.
- DAViCal IRC Channel can be a good place to get quick interactive help, though sometimes it may take a few hours for the developers to respond if your problem is an especially interesting one.
- DAViCal Mailing Lists have subscribers who have been happily using DAViCal for years, and may well have seen your problem.
- Support is available in other ways as well.
